Paratype, 1 ♀ (on slide under four coverslips, slide No. EUL.237), INDIA: UTTARAKHAND: Dehradun, Malsi , 4.xi.2009, Coll. F. R . Khan. ( ZDAMU).

Diagnosis: Omphale ecola Jamali & Zeya sp. nov. is a distinctive species, comes close to O. prabha Narendran in having fore wing infuscate beyond speculum. However, it differs from the latter in following characters: antennal flagellum with 3 anelli; fore wing with apical margin slightly narrower, speculum closed; radial cell bare. In O. prabha : antenna with 1 anellus; fore wing with apical margin rounded, speculum opened; redial cell setose.

Description: Female: Body length, 0.7–0.8 mm (holotype, 0.8 mm). Head dark brown with greenish reflection. Antenna pale brown to brown. Mesosoma dark brown with greenish reflection. Wings hyaline; fore wing ( Fig. 1E) with a brown infuscate band below marginal vein extending to posterior margin of disc. Legs largely with pale white to pale brown except fore and mid coxae, hind femur and hind tibia brown and hind coxa dark brown. Gaster metallic brown.

Head ( Fig. 1A), in frontal view, 1.4× as broad as high; smooth except vertex with transverse striations; eye height 3.7× as long as malar space; scrobal grooves joining frontal groove separately; mandible with many teeth, ventral two teeth are larger than others as in Fig. 1B; clypeus semicircular, 1.7× as broad as high; antennal toruli situated slightly above the lower eye margin. Antenna ( Fig. 1C) with scape 5.5× as long as broad, 2.4× as long as pedicel; pedicel 2.3× as long as broad; pedicel + flagellum 2.7× as long as distance between eyes (55: 20); flagellum with 3 distinct anelli; Fu1 subequal to Fu2; Fu1 1.2× as broad as Fu2; Fu3 and Fu4 individually shorter than Fu1 individually; clava 3.2× as long as broad; all flagellomeres with long sensilla except anelli.

Mesosoma ( Fig. 1D) almost smooth, 1.4× as long as broad; pronotum very narrow, not visible in dorsal view; mesoscutum shorter than mesoscutellum; notauli incomplete, present in anterior third; mid lobe of mesosctum with 2 setae, lateral lobe with 1 lateroposterior seta; axillae elongate, extending posteriorly more than two-thirds length of mesoscutellum; mesoscutellum longer than broad with 2 long setae, each seta near lateral margin; dorsellum 0.38× as long as broad, and 0.58× as long as median length of propodeum; propodeal callus with 2 short setae. Fore wing ( Fig. 1E) 2.6× as long as broad; speculum closed; admarginal setae 6 arising from marginal vein; radial cell bare; marginal vein + parastigma 1.4× as long as submarginal vein, 5.4× as long as stigmal vein; post marginal vein very short, about one-fifth of stigmal vein; stigmal vein slender; longest marginal seta 0.44× maximum wing width. Hind wing ( Fig. 1F) 6.1× as long as broad with apex pointed; longest marginal seta 1.06×as long as maximum wing width.

Metasoma ( Fig. 1G). Petiole as long as broad; gaster shorter than mesosoma; ovipositor occupying more than half of gaster length, hardly exserted beyond apex of gaster; ovipositor 1.55× as long as hind tibia.
